After 15 years of dominating the police-cruiser market, the Ford Crown Victoria-based Police Interceptor will be retired in late 2011. Since 1996, when GM stopped building the Chevy Caprice, Ford's hasn't had much competition in the police-car niche, as about 85 percent of the 75,000 police cars currently sold in the U.S. are "PI's."
But now police agencies all over the country will have some big decisions to make, and plenty of options as they look for replacements. Last October and November, General Motors and Ford both announced plans for all-new police cars that will be "purpose-built" -- that is, specifically designed and built as police cruisers. Today's police cars have been, for the most part, tuned versions of normal street cars.
